Changes between Initial Version and Version 1 of Ticket #67802, comment 2

initial	v1
1		Clang since 3.9.0 ([https://github.com/llvm/llvm-project/commit/9e7d0a98fa26]) but before 9.0.0 ([https://github.com/llvm/llvm-project/commit/6d9fb68c536d], and so likely also Xcode Clang before 11.4) had defined `_mm256_maskz_cvtps_ph` as 2-argument (and apparently so had Intel for a time, but not anymore). It should be okay to use the equivalent `_mm256_maskz_cvt_roundps_ph` intrinsic which Clang has always defined as 3-argument: [https://github.com/macports/macports-ports/pull/19627]
